[dpdk-dev] [PATCH v2] drivers/crypto: fix build with make 4.3

[Thomas Monjalon <thomas@monjalon.net>]

In the check for the version of intel-ipsec-mb library,
there is a backslash in front of the #include.
This backslash is for escaping the hash sign parsed as
a number sign in make.

Since make-4.3, escaping is not required for the number sign.
As a consequence, it resolves now to '\#':

syntax error near unexpected token `|'
`grep -e "IMB_VERSION_STR" \#include <intel-ipsec-mb.h> | cut -d'"' -f2'
syntax error near unexpected token `|'
`grep -e "IMB_VERSION_NUM" \#include <intel-ipsec-mb.h> | cut -d' ' -f3'

The makefiles are fixed by using a variable for the hash sign,
as recommended in make-4.3 changelog:
	https://lists.gnu.org/archive/html/info-gnu/2020-01/msg00004.html

Fixes: 3067c8ce77ac ("crypto/aesni_mb: fix build with custom dependency path")
Fixes: 457b8e372975 ("crypto/aesni_gcm: check dependency version with make")
Fixes: bf6eb2c22fd1 ("crypto/kasumi: use IPsec library")

v2:
- found the root cause in make-4.3
- use $H for compatibility with make < 4.3

Note the list of "Fixes" references are here to help backporting,
even if there was no bug before the recent release of make-4.3.
